How to send push to specific member using SNS topic? - amazon-web-services

Question

I am using AWS SNS to send a push notification, right now i am using publish method of aws-php-sdk to send push specific device. My requirement is sent push to thousands of members within 30 seconds. When i used publish method it takes 5min to send 1000 users.
I have read about topic it sends multiple members at once, but my scenario is i want to send push to specific users, not all topic users.
For example, i register 10,000 members in one topic, but from this 10,000 some time i am sending 9000, sometimes 1000 members.
So anyone has an idea how to send push using topic but specific members only.
I also think another case, every time i create new topic and register member to this topic and then send a message to him and then delete topic, but here every time when register member it is also taking time. So if you have an idea to register multiple members at once then it will also be helpful for me.
Below is my current code to send push.
$arn = "user arn";
$sns = new Aws\Sns\SnsClient(array(
'version' => 'latest',
'key' => my_aws_key,
'secret' => aws_secret,
'region' => region,
'profile' => profile_name,
'debug' => false,
'http' => array('verify' => false)
));
$appArn = "application arn";
$sns->publish(array('Message' => '{ "GCM": "{\"data\": { \"message\": \" This is my message \"} }"}',
'MessageStructure' => 'json',
'TargetArn' => $arn
));

I would recommend to use publishAsync() method.
$userArnCollection = array(
'arn:XXX',
'arn:YYY',
'arn:ZZZ',
);
$sns = new Aws\Sns\SnsClient(array(
'version' => 'latest',
'key' => my_aws_key,
'secret' => aws_secret,
'region' => region,
'profile' => profile_name,
'debug' => false,
'http' => array('verify' => false)
));
foreach ($userArnCollection as $userArn) {
$sns->publishAsync(array(
'Message' => '{ "GCM": "{\"data\": { \"message\": \" This is my message \"} }"}',
'MessageStructure' => 'json',
'TargetArn' => $userArn
));
}
EDIT
Example with promise handling
$userArnCollection = array(
'arn:XXX',
'arn:YYY',
'arn:ZZZ',
);
$sns = new Aws\Sns\SnsClient(array(
'version' => 'latest',
'key' => my_aws_key,
'secret' => aws_secret,
'region' => region,
'profile' => profile_name,
'debug' => false,
'http' => array('verify' => false)
));
$promises = array();
foreach ($userArnCollection as $userArn) {
$promises[] = $sns->publishAsync(array(
'Message' => '{ "GCM": "{\"data\": { \"message\": \" This is my message \"} }"}',
'MessageStructure' => 'json',
'TargetArn' => $userArn
));
}
$results = \GuzzleHttp\Promise\unwrap($promises);

After trying many solutions i am able to send thousands of notification within one minute, here i am showing code how i do it, I have done with php multicurl functionality, so i execute multiple parallel processes and all process send notification simultaneously.
Define multi curl and prepare URL to send notification
Suppose i have 5,000 members and i have array of it's token and other member details $device_type_ids_arr
I part of all member to 500 bunch, so each time curl execute it sends notification to 500 members
$_datas = array_chunk($device_type_ids_arr, 500);
/*initialise multi curl*/
$mh = curl_multi_init();
$handles = array();
/* Perform loop for each 500 members batch */
foreach ($_datas as $batchPart) {
$ch = curl_init();
$postData['devices'] = $batchPart;
$postData['push_content'] = $push_content;
$data_string = json_encode($postData);
curl_setopt($ch, CURLOPT_URL, base_url() . "EmailPipe/sendNotification/"); //your URL to call amazon service (Explain below)
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_USERAGENT, 'User-Agent: curl/7.39.0');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length:' . strlen($data_string))
);
curl_multi_add_handle($mh, $ch);
$handles[] = $ch;
}
// execute requests and poll periodically until all have completed
$isRunning = null;
do {
curl_multi_exec($mh, $isRunning);
} while ($isRunning > 0);
/* Once all execution are complete remove curl handler */
foreach ($handles as $ch) {
curl_multi_remove_handle($mh, $ch);
}
/* Close multi curl */
curl_multi_close($mh);
Function which is received curl request and send notification
function sendCurlSignal() {
require_once APPPATH . 'libraries/aws-sdk/aws-autoloader.php';
$pipeArr = json_decode(file_get_contents('php://input'), true);
